Floods, particularly fast ones, are recurrent natural disasters with a large impact on people and infrastructures. In order to mitigate their impact most countries created regulatory frameworks to coordinate the large number of actors participating to the response of these crises. Several levels from rescue to infrastructure restoration are involved. This article proposes to improve the management of risk and resilience in areas subject to flash floods. The innovative autonomic approach presented in this article is twofold: A short-term feedback loop using a large range of information to help managing the current flood; A long-term feedback loop aiming at improving the resilience of the area to reduce the impact of future crises. The originality of these two loops consists in their link which helps improving the quality of both by feeding each other. This article also describes a scenario showing several benefits of the proposed approach.
